Perfect to easily identify first aid trained staff, especially if there is an emergency.

The stickers from RainbowSafety did the job on our site in Edmonton: they were easy to apply and the “First Aid” label is visible from a distance. They survived some rainy days without peeling. That said - after heavy rain and on some plastic helmet surfaces the edges started to lift slightly. For indoor or typical outdoor use they’re fine; for long-term heavy-duty exposure I'd prefer a more heavy-duty sticker or maybe a rigid helmet badge. Still a solid pick for many worksites.

These helmet stickers do exactly what they’re supposed to: they stick on easily and make first-aiders obvious. The size (50 mm square) is fine and they stayed on helmets through several weeks outside. My only wish is that the pack included more than 10 - for larger crews 10 goes quickly. Otherwise a useful and reasonably priced solution.

We use these First Aid helmet stickers at a construction project in Vancouver. They arrived quickly, application was simple, and the “First Aid” lettering is bold and legible. They’ve stayed firmly glued even through a few rain showers and chilly temps. Definitely helpful for safety and makes it easy for workers to know who to find if someone gets hurt. I’d buy these again

I grabbed this 10-pack of First Aid helmet stickers for our job-site in Toronto and they’re exactly what we needed. The 50 × 50 mm size is perfect for hard hats — not too big to look bulky, but large enough to spot from a short distance. The self-adhesive vinyl stuck on easily (just cleaned the helmet first) and has held up well through rain and cold weather. It helps everyone on site quickly identify our certified first aiders in case of emergency. Solid product - good value for a small crew.
